Fremantle Dockers coach Ross Lyon has agreed to a two-year contract extension at the club.

Lyon is currently mid-way through a four-year deal signed in 2011, but has recommitted to the club until the end of the 2017 AFL season.

Lyon is a revered coach throughout the AFL, coaching in four grand-finals in the last five years, and has said the promising future of his Dockers team had an influence on his decision to extend.

"We are in the business of building a great club and I know everyone at the club - players, coaches, administration staff and commercial operations - are trying to take that next step and continue to build," Lyon said in a statement.

"We are here to build a great club and great clubs win premierships and that's what we want to be."

Fremantle chief executive Steve Rosich has expressed his pleasure at Lyon's decision, and believes it is indicative of the positive direction the club is heading in.

"Ross' work ethic, expertise and determination to excel in all areas of football have had a tremendous influence throughout the club, as evidenced by our recent success including playing finals in consecutive years for the first time and playing in the 2013 grand final," Rosich said.

"Ross is a highly motivated and driven person who has many fine traits that we believe are the right combination to maximise our potential on the field."

Sandilands to finish career a Docker

The Dockers have also signed star ruckman Aaron Sandilands on a one-year contract extension, indicating that his career may come to a close at the conclusion of the 2015 season.

Sandilands was to be out of contract at the end of this season, but he has joined Lyon in committing to an additional period at the club.

Sandilands, who began his Fremantle career on the rookie list, said his love for the game and the club made the decision easy.

“I’m still loving my footy and it’s great that the club wanted to extend my contract for another 12 months,” Sandilands said.

“The playing group and the coaching group are all driven and I’m really enjoying coming to training.

"Fremantle were the ones that gave me the opportunity back in the day by putting me on the rookie list and it’s great that I’ll finish my career here.”
